I was surprising myself every new cold day...

I was surprising myself every new cold day trying to find the upper limit of what it liked while programming cold-start parameters.

It's summer, I don't have to worry about it for another 6 months or so...I was thinking I could use the interval to bone up on some theory.

The engine is nothing remarkable chamber design-wise: edelbrock aluminum heads, so a common FE wedge chamber. Bore is 4.125. Not measuring timing off the balancer, it's got a crank trigger and wheel and other than being high, everything seems to be reading correctly.

So what you're basically saying is every engine is different and I need to keep changing, checking and adjusting timing for my particular engine. No nice web-calculators out there where I can plug in bore, stroke, cam profile, etc and see a nice baseline advance curve, albeit, one that might still require some fine-tuning.

Thanks
